Securtiy at Contiki camps/hotels

Just wondering what the security is like at the places we stay. I have 2 passports (one NZ & one EU) and don't want to carry both around all the time. I was wondering if the paces we stay on concept trips have reliable secure places to store belongings ( like a safe at reception or something). If so i thought it would be a good idea to put one passport there and carry the other to reduce the risk of losing both of them. Also what is the secuity like in the rooms for our bags etc.

I just came back from the European Whirl and there were always locks on the doors with the exception of the chalet in Switzerland – in the rooms there there were cubbies to lock up your stuff. In the Contiki resorts there really wasn’t a front desk or anything – just a mess tent…
